| Source measurement | — | Roughly, there are two groups in the Dutch parliament – one in favor of replacing the Walrus class by an equally capable class of large, expeditionary, diesel-electric submarine, and the other in favor of choosing a cheaper solution of smaller diesel-electrics, similar to Swedish and German submarines.[source]Orka-class submarine · History / Continued delays; only the objects and conditions stated in this passage Damen Group and Saab Group announced that they have partnered from 2015 to jointly develop, offer and build next-generation submarines that are able to replace the current Walrus -class submarines. It was announced on 1 June 2018 that their design will be derived from the A26 submarine . The proposed submarine is around 73 metres (239 ft 6 in) long with a beam of 8 metres (26 ft 3 in). Furthermore, the displacement will be around 2,900 tonnes (2,900 long tons ), with a complement of 34 to 42 people. The boat's armament includes six torpedo tubes and one multi-mission lock which can be used to deploy special forces. On 28 July 2023 they submitted a submarine design for the Walrus class replacement program that is called C718. The offer includes knowledge transfer so that the Royal Netherlands Navy can perform maintenance and upgrade the submarines during their lifespan by themselves.[source]Orka-class submarine · History / Contenders; only the objects and conditions stated in this passage |
